Abstract[English]
The present invention relates to the technical field of organic photoelectric materials, and particularly relates to a triazine compound, and an OLED and an organic light-emitting device comprising same. In the triazine compound of the present invention, by taking a triazine structure as a core, an aryl and an alkyl are combined with a fluorenyl to form a side chain combination, such that the compound has an excellent light-emitting efficiency and relatively good thermal stability. In addition, applying the triazine compound provided in the present invention to an apparatus can effectively enable the organic light-emitting apparatus to have a lower driving voltage and maintain voltage stability. In addition, the light-emitting efficiency is improved, the operating life is significantly prolonged, and thus the triazine compound has very good application prospects.[French]
La présente invention relève du domaine technique des matériaux photoélectriques organiques, et concerne en particulier un composé triazine, une DELO et un dispositif électroluminescent organique la comprenant. Dans le composé de triazine selon la présente invention, une structure de triazine est utilisée comme noyau, un aryle et un alkyle sont combinés avec un fluorényle pour former une combinaison de chaîne latérale, ce qui permet de conférer au composé a une excellente efficacité d'émission de lumière et une stabilité thermique relativement bonne. De plus, l'application du composé triazine fourni dans la présente invention à un appareil peut permettre efficacement à l'appareil électroluminescent organique d'avoir une tension de commande inférieure et de maintenir une stabilité de tension. De plus, l'efficacité d'émission de lumière est améliorée, la durée de vie est significativement prolongée, et ainsi le composé de triazine présente de très bonnes perspectives d'application.[Chinese]
本发明涉及有机光电材料技术领域，尤其是一种三嗪类化合物、具有该化合物的OLED和有机发光装置。本发明的三嗪类化合物，通过三嗪结构为核心，由芳基与烷基结合芴基基团形成侧链搭配，使化合物具有优异的发光效率以及较好的热稳定性；同时本发明所提供的三嗪类化合物作用于器件，可以有效地使有机发光器件具有更低驱动电压且保持电压的稳定性，且发光效率提高，工作寿命得以明显延长，具有很好的应用前景。
